Specification of Letters Patent.

Patented May 19, 1908.

Application filed March 24, 1908. semi No. 422,871.

To all whom it may concern:

Be it known that 1, DAVID iins'xicm', of borough of Brooklyn, county of Kings. and State of New York, have invented a. new and useful Improvement; in Linotype-Machincs, of which the following is a specifimition.

This invention relates to linger-key mechanism, commercially known a keyboard mechanism, of the character shown in Letters Patent of the United States to P. T. Dodge, #530,931, used for operating the escapements which release the matrices in Mergenthaler line casting machines. In this mechanism, the escapement-actuating reeds are lifted by underlying pivoted yokcs which carry lifting cams arranged to ride upon underlying continuously driven rubber rolls, the fall ol' the yokes and the contact of the cams with the rolls being controlled by tinger-keys. The various parts of this mcchanism are of such character that they require to be inspected, cleaned andlulnicatcd at reasonable intervals. Heretofore, the framework supporting the operating parts has been built up in such manner that access to the interior was not easily obtained.

My invention consists in a. construction which permits the instantaneous removal of the yokes and cams in series so that they may be conveniently dealt with away from the machine, and so that the reeds and their connections, although accessible, remain in their operative positions in the machine.

My invention also consists in improved means for locking the lingei kcys to prevent their accidental movement.

In the drawings,Figure 1 is a perspective view of the keyboard constructed in accordance with my invention, the two members which sustain the reeds, yokes, etc, being removed from the central frame in which the reeds are sustained. Fig. 2 is a perspecli e view of one ofthe locking bars. l igjfl is'an end elevation of the mechanism with the parts in operative position. Fig. st is a view on. a larger scale, of the inside of the keyboard cam frame, looking in the direction of the arrow, 1 ig. l, and showing the locking strip in position to hold the triggers.

Referring to the drawings, A represents a 1 row of vertically guided reeds by which the cscapements of the-magazine are actuated.

B, B, represent a series ol-cam yokes ar-- ranged in two series, their outer ends being pivoted at l), I), and their inner ends arranged beneath the successive reeds A for the purpose of lifting the same.

t, (7, are vertical cams, pivoted one in each of the yokes. i

l), l), are horizontally contiiu ously rotating rubber rolls arranged one beneath each row of cams t.

E, E, are angular levers or triggers arranged to sustain the inner ends of the yokcs B above their lowermost positions for the purpose o" holding the cams normally out of contact with the underlying rolls, the cams at such time being prevented from rotating by stationary stop-pins l in the frame.-

G are vertically guided bars connected one to each of the triggers, and also connected one to each of the linger-key levers ll. "hen a' linger key is depressed, it will cause the bar G and the trigger E to release the end of the yoke B, which falls until its cam (I) encounters the underlying roll; The l'rictional engagement between the roll and cam causes the latter to turn. By reason of its irregular or eccentric form, the cam in turning, lifts the yoke to or above it's normal position, causing it in turn to lift the reed A. As the yoke falls, it is arrested in its original position by the trigger E at or about the same time the cam C is held from rotation by the stop pin, and thus kept out of contact with the roll. The foregoing parts are all of essentially the same construction as in the patent rcferrid to.

in carrying my improvement into ellect, 1 mount the reeds A and slides G in a fixed vertical central framework I, having hori Zontal guides to receive them, so that they may be maintained in their operative POSP tions in the macliineaml in proper relation to each other after thcother parts of the mechanism are removed.

For the purpose of supporting the rolls, the cam yokcs, and the triggers, I provide two subsidiary frames J and J, which are removably secured to opposite sides of the frame i. These two subsidiary ll'z-fnics,

which are preferably alike in form, are co structed as shown, with the necessary been iugs for the rolls, and vertical guides am. supports for the yokes and-triggers. Each of the subsidiary frames with the contained parts constitutes a unitary structure which may be applied to'and removed from the frame, which is provided i their inner ends machine at will without disturbing the relation of thecontained members. The subsidiary frames are preferably made as shown, with. vertical faces to with dowel-pins t, t z. lute-r correspondinghholes in the removable frames, so that when t ese frames are applied to the central frame, gcrs will be brought in proper relations to the reeds A and slides (1 The subsidiary frames may be secured in position by any means which willadmit of their instantaneous disconnection. I refer to employ for the purpose gravitating iooks K ivoted at to the central fiame and arranged to engage at their outer ends over pins or studs on the removable frames.

The foregoing construction will admit of I either set of yokes and the cooperating parts being instantly removed from the machine and instantly re-applied without disorganizthe machine.

trigg positlon,

ing or disarranging1 the other parts.

When the su si iary frames are removed, it is desirable to prevent the tri gers E from being actuated so as to permit t e fall of the yokes, as this would, to an extent, interfere with the speedy restoration of the parts to I therefore mount in each of the subsidiary frames, over the lower ends of the tri gers, a transverse sliding bar M, notche 1n the under side so that when in one with the notches overlying the ers, the latter are permittedjto operate, and when in another position, with the notches out of line with the triggers, the latter are locked from movement. These bars are set in the removal of the frames. When the parts are in position on the machine, these locking bars serve also, through the triggers, as a means of locking the finger-keys so that there is no dan er of the matrices being accidentally re eased.

For the purpose of locking the bars M in triggers,

their operative and propose to provide them each in the upper I side with notches m to receive pivoted hand this twelfth day of March,1 latches m on the ends of the frames J, as 1 presence of two attesting and 4. The movement of shown in Figs. 1

It will of course 'be'understood by the skilled mechanic that the subsidiar frames may be modified in form, and that t ey may be secured by fastening devices other than i those shown, provided the mode of action and the results herein described are retained. Having thus described my invention,

by Letters Pat- 1. In a keyboard mechanism of the class described, a central frame provided-with guides for the vertical reeds and slides, in combination with the instantly removable subsidiary frames a plied thereto, and means for securin said Frames in position, each subsidiary ame containing a roll, a series of cam yokes, and a series of triggers.

2. In combination with the fixed central frame I and vertically uided reeds therein, the subsidiary framesl each containing a roll, cam yokes and triggers, means for locating said frames in relation to the main-frame, and manual devices for securing the subsidia their instantaneous release.

3. In a machine ofthe class described, the fixed central frame with vertical slide; therein, in combination with the instantly detachframes in position and permitting able subsidiary frames each containing a roll, a series of yokes, a series of triggers, and means for locking the trig ers in series.

4. In a marlnne of the c ass described and in combination with a'stationary frame c0ntaining vertical slides, an instantly removable subsidiary frame, said subsidiary frame containing a roll, a series series of triggers, and a sliding notched bar to lock the tri gers.

5. In a key oard mechanism of the class described, an independently removable frame containing a and hieans for locking the same in for restoration to the machine;

In testimony whereof I hereu to set my 08, in the witnesses.
